Horsepower #'s on Cub

Anytime you take a motor designed to make 33 to 35HP and triple that...yeah, it won't be as reliable as stock. That can be said about anything.

 

I would say for the money....you get the most HP for your buck out of a cub.

It definately makes more power out of the box than the TRex or Vito's monoblock...both need some extensive porting to catch up, whereas the cub needs a cleanup port.

 

Larger stroke normally gives you more torque than HP...but, of course, HP increases as well.

 

If money wasn't an object, my next motor would be a cheetah cylinder....they have power valves....and run very hard.

 

I think you're confused.... A longer rod on a stroked crank makes it more reliable...

The longer rod cuts down on the angle as the piston travels up and down, creating less stress on all parts involved...but, especially the piston. It's not trying to shove the piston through the cylinder wall quite as much....

 

I'm not trying to steer you away from a cub, they're great and I'm happier than shit I built mine.

However...you mentioned budget. I don't think you'll be as happy on that budget as you would be with a set of good ported stock cylinders....

But he will more than likely be happier in the long run, who leave their bike alone long enough anyway? Even on a budget I would rather have the cub cylinder, with his existing part he will have room to grow.

ONthat....

 

1 answer, Jeff at FAST. He can hook you up with all of it.

 

However...if youre gonna do it, I'd do it right. get a smaller dome and run 100% race gas.

I know, I know...it'll cost a little more. But, it'll save the aggravation of mixing each time out....

 

Jeff will tell you cubs love compression... And I'll tell you they LOVE timing, too...

I think between the two, it's worth the race gas.

 

Then it'll be alky...then it'll be....lol...

 

You're gonna have fun, no doubt.
